Characteristics of Styrene-Butadiene Rubber/Silica/Nanoprene Compounds for Application in Tire Tread

Abstract

Nanoprene is made from chemically cross-linked rubber particles, and has many hydroxyl groups on the surface of the particles. It is speculated that the Nanoprene could reduce the silica-silica network formation by introducing hydrogen bonding between the silanol group of silica and the hydroxyl group of Nanoprene. In this study, the styrene-butadiene rubber (SBR)/silica compounds with two types of the Nanoprene (BM75OH, BM15OH) were evaluated and it could be well explained by the concept of the volume fraction of filler or the volume fraction of rubber. If the Nanoprene applied to the compound is considered as a kind of filler, the minimum torque values and bound rubber contents of the un-vulcanized compounds, the swelling ratio and the stress-strain relationship of the vulcanized compounds could be well explained by the volume fraction of filler (phi(F)). If Nanoprene is considered as a kind of rubber such as SBR, the properties such as peak tan delta, Payne effect, tan delta at 0 degrees C and 60 degrees C, and abrasion resistance could be well explained by the volume fraction of rubber (phi'(R)). However, the improvement of silica dispersion by addition of the Nanoprene particles in the compounds was not significant. The application of BM75OH as a polymer to the tread compound will be suitable for winter tires. In addition, the compound with BM15OH as an additive will be suitable as a tread compound for summer tires.

Aramid Nanofiber Reinforced Rubber Compounds for the Application of Tire Tread with High Abrasion Resistance and Fuel Saving Efficiency

“…These results conclusively indicate the positive effect of the fANFs on the abrasion resistance of rubber compounds. It is known that the abrasion resistance can be enhanced by improving the dispersion of the filler or increasing the rubber–filler interaction. , In addition to the beneficial features of ANFs, such as excellent mechanical properties and a high specific area, the functionalization using the silane coupling agent allows for covalent bonding between the fANFs and rubber matrix. The TESPT-functionalized ANF surface also improves the dispersion of the fANFs, which have a hydrophilic chemical nature, in the hydrophobic rubber matrix.…”

Design of convex‐hull bionic tire tread compounds and mechanism on collaborative improvement of wet resistance and wear resistance

“…The existing research on collaborative improvement methods of wet resistance and wear resistance focuses on tire tread compound composition, tire structures and tread patterns. Wear resistance and wet resistance can be collaboratively improved by adjusting the ratios of rubbers to fillers or by adding new materials to alter the composition of tire tread compounds 9 . As for rubbers, the development of butadiene rubber (BR) has largely improved the wear resistance of tire tread compounds, but the wet resistance is low 10,11 .…”

Synthesis and Application of Copolymers Based on Styrene, Divinylbenzene and Functionalizing Monomers

“…Many tire rubber properties such as tensile properties, heat build-up, viscoelastic properties, and abrasion could be improved by using the polymer additive. This additive is a kind of micro-gel which was produced as cross-linked rubber particles [2]. The spherical particles have a diameter of about 40 ~ 65 nm and a very narrow particle size distribution.…”
